Who WANTS Secure Calling

• Barack Obama (and others) national security,
  public safety
• Utilities operational security, homeland
  security
• Legal protecting confidentiality, negotiations
• Large Manufacturers competitive and HR info
• Medical privacy (Hippa), medical records and
  messaging
• Financial deal secrecy, confidentiality

How did BBTelsys get started?

• Working with Ingate since 2003 (early adopter)
• Putting the tools in place to secure networks
• Respect for securing the network
• Dont let VoIP be a tempting target for hackers
• The business customer expects 99.999 up-time. It
  is a mission critical application.
• Well managed IP infrastructure is essential.
• Interaction with Customers Asking the Customer
  What If
• Our strategy is to search for differentiators
• Secure calling is a niche but significant unmet
  need

What Ingate Brought to Our Attention

• Signaling and Media flow separately
• TLS/SRTP (Transport Layer Security/Secure Real
  Time Protocol) could provide the right and
  sufficient encryption for the dynamics of VoIP
  application (although not widely used)
• Low Overhead
• High number of small packets
• Dynamics of both TLS (on signaling) and SRTP
  (media) creates a high level of difficulty to
  crack decoding encryption

8
Flexibility of Ingate SIParators

• Decrypt/encrypt both TLS and SRTP streams to and
  from the PBX
• Decrypt/and then re-encrypt for end-to-end
  solutions
• Pass the media in its encrypted state without
  decrypting

9
Whats Wrong with Most Data Encryption Technology

• Developed for data, long packets
• The more complex the better
• Time delay doesnt impact use

High Overhead Produces Delays Which Interrupts or
Downgrades Voice Quality
10
What Devices Can Use TLS

• Ingates Edge Devices
• TLS aware phones
• Polycom
• Aastra
• Snom

11
Where are Customers Vulnerable

• The customer is most vulnerable to espionage at
  his internet connection
• Most existing PBXs do not allow for encryption

Confidentiality on the Internet

TLS End-User/Carrier Results

• Quality of Call Maintained, no noticeable
  influence or delay
• Approximate Bandwidth Overhead appears quite low
  (but has not been measured?)

15
BBTelsys is Open for Business

• BBTelsys offers TLS Test Calling Today
• SIP Trunks
• Hosted Plans
• The Opportunity for a Reseller or End-User
• Secure calling is a differentiator
• Major accounts interested
• Separate yourself from the competition with
  BBTelsys

16
Future Secure Calling Developments

• Secure solutions for the Mobile Worker
• Current wireless networks frequently unsecured.
• a major worry for security conscious
• Opportunity initially with softphones to provide
  similar security
• Future solutions on smartphone with fixed-mobile
  convergence running VoIP phone (ala Presidents
  Blackberry?)
